CV 3 Anatomy of the Cardiovascular System & Flow of Blood
• • •
Right Heart and Left Heart Flow of Blood through Heart Components of Vascular System • Arteries – Aorta, Large Arteries, Small Arteries • • • • • Distributing network
Arterioles – Resistance Vessels Capillaries – Exchange Vessels Venules & Small Veins – some exchange, capacitance vessels Large Veins and Inferior and Superior Vena Cava – Collecting Vessels returning blood to the heart.

CV 4 Specialized Cells and Structures within the Heart
Specialized Cells – cells with differing properties and functions • • • • Muscle Cells – Contractile Proteins & Generate Pressure. Atria & Ventricles Pacemaker Cells – Self Depolarize and Initiate Activation Heart Purkinje Fibers – Cells Specialized for Rapid Conduction Cells in AV Node – Slow Rate of Rise and Low Amplitude à slow cell to cell spread of activation.
Specialized Structures within the Heart • • • SA Node – Activation normally originates from Pacemaker Cells Localized here. Internodal and Interatrial Preferential Conduction Pathways AV Node – Site conduction delay in atrioventricular activation. Filter atrial arrythymias from ventricles. Contains some Pacemaker Cells. His Bundle &
